Why Choose OUKAMU Low Voltage Cable Joint Connectors?
Our branch joint systems represent a breakthrough in cable T-connection technology. Unlike traditional splicing methods that require cutting and stripping both cables, OUKAMU connectors maintain the main cable's integrity throughout installation.
The uncut main cable design preserves 100% of the original current-carrying capacity. This eliminates voltage drop issues commonly associated with conventional splice connectors. Your power distribution network maintains optimal electrical performance without creating unnecessary failure points.
Installation flexibility sets our product apart. You can position branch connections anywhere along the main cable route without pre-measuring or customization. This on-site adaptability reduces planning time and accommodates last-minute layout changes during construction.
The integrated sealing system protects against water ingress, dust contamination, and environmental degradation. Our two-part polyurethane resin encapsulation creates a permanent barrier suitable for cable wells, underground burial, and exposed bridge installations.
Three Protection Levels for Every Environment
Flame-Retardant Series
Our ZR-rated connectors prevent fire propagation along cable routes. The self-extinguishing resin compound stops flames within 60 seconds of ignition source removal.
This protection is essential for commercial buildings, residential complexes, and public facilities where fire safety codes mandate flame-retardant materials. The sealed design prevents exposed conductors while maintaining aesthetic appearance in visible installations like cable bridges and trunking systems.
Waterproof Series
The IP68-rated waterproof Low Voltage Cable Joint Connector withstands continuous submersion up to 2 meters depth. Our integrated potting process eliminates air pockets where moisture could accumulate.
Applications include underground direct burial installations, submerged cable wells, metro tunnel systems, and coastal infrastructure exposed to saltwater environments. The connection remains stable through decades of moisture exposure without corrosion or insulation breakdown.
Fire-Resistant Series
Fire-resistant models maintain circuit integrity for 90-180 minutes during active fire conditions. The specialized ceramic fiber reinforcement keeps conductors operational even when external temperatures exceed 950°C.
Critical safety systems benefit most from this protection: emergency lighting circuits, fire alarm networks, smoke extraction controls, and escape route signaling. Your life-safety systems continue functioning when they're needed most.
Wide Application Across Infrastructure Projects
More than 10,000 important projects have been implemented with OUKAMU product systems, both in China and elsewhere. Our products have been demonstrated to be reliable in difficult situations such as the sea environment of Hong Kong-Zhuhai-Macao Bridge and the vibration environment of the Zhengzhou-Wanzhou High-Speed Railroad.
Our Space saving design is an advantage for metro systems in busy cable galleries. The tiny joint profile fits ordinary cable trays without the need for huge access pits. Our connectors are widely used in the distribution network of Nantong Metro Line 2.
Installation flexibility is a plus for commercial and residential developers. Xi'an Olympic Village and Shaanxi Olympic Sports Center chose our systems for their safety certification, beautiful enclosed design and maintenance-free operation.
Flame retardant characteristics are desirable for industrial facilities in areas with combustible materials. Our ZR-rated versions are specified by manufacturing plants, chemical processing facilities and warehouse distribution centers for regulatory compliance and insurance needs.
Installation Advantages That Save Time and Money
old fashioned cable splicing involves cutting the main cable, stripping insulation from the two pieces, placing conductors into barrel connections, crimping them with specific tools, and then wrapping several layers of insulation tape. This produces mechanical weaknesses and possible failure areas.
OUKAMU's breakthrough design means no wires to snip. You just push the connection housing over the main cable, stab thru the insulation where you want to branch off, insert the branch cable, then pour in the encapsulating epoxy.
The time savings are significant. The traditional process requires 45 to 60 minutes each connection with a two-person crew. Our technology finishes installations in 15-20 minutes using a single professional. This efficiency saves thousands of dollars in labour on projects requiring dozens of branch connections.
Material savings are an additional economic gain. Since the primary cable is not cut, you remove the 2-3 metre waste usually needed for working length at each splice point. The savings you get on one job with our cable more than pays for the extra cost of our connector technology.
FAQ
Q: What is the difference between a cable joint and a splice connector?
A: A traditional splice connector requires cutting both cables and creating a butt connection where conductors meet end-to-end. A cable joint, particularly our branch design, connects cables without cutting the main conductor. This maintains the main cable's electrical and mechanical properties while adding a branch circuit. Our system is technically a tap connection rather than a true splice.
Q: How long can low voltage cables run before requiring joints?
A: Standard 18AWG low voltage wire runs effectively up to 300 feet, while 16AWG extends to 400 feet before voltage drop becomes problematic. However, our branch joints don't extend circuit length—they add distribution points. Since we don't cut the main cable, the total circuit length remains unchanged. You're simply adding outlets along an existing run rather than extending it.
Q: Does your branch joint system reduce voltage in the main cable?
A: No. Unlike traditional splices that introduce resistance at the connection point, our piercing connector design maintains continuous conductor contact. Independent testing shows voltage drop across our joints measures less than 0.02V at rated current—negligible in practical applications. The uncut main cable preserves full current-carrying capacity without the micro-welds and crimp points that create resistance in conventional splice connectors.
Q: Can these connectors be reused if cable layout changes?
A: The mechanical connector components are reusable, but the encapsulation resin is permanent once cured. For temporary installations or layouts likely to change, we recommend our mechanical-seal models that use compression gaskets instead of resin potting. However, resin-sealed joints offer superior long-term reliability and environmental protection for permanent installations.
Q: What certifications do your products hold?
A: Our product systems comply with GB/T 14048.7-2016 standards for low-voltage switchgear and controlgear assemblies. We maintain ISO 9001 quality management certification and hold over 150 invention patents protecting our proprietary technologies. Product testing documentation is available upon request for projects requiring specific compliance verification.
Q: How do I select the correct model for my cable sizes?
A: Match the connector model number to your main cable cross-sectional area (the first number) and branch cable size (the second number). For example, model ZR-JFZ-240/70 accommodates main cables from 95-240mm² and branch cables from 6-70mm². If your specifications fall between models, always size up to ensure adequate conductor contact and resin coverage. Our technical team provides selection assistance for complex installations.
